Of all the domino users I know in person, none has both models. That says about how common or uncommon people own both models for the sake of keeping just one setting in each model.
I realize we have never met, but I own both models and use both when appropriate for the project. The DF 700 was my first Festool purchase. At the time, I wanted it for a large gate and fence project and the 14mm loose tenons were a perfect choice for me. I've used it since on large interior projects and have no intention of getting rid of it.
Later I bought the DF 500, and use it in almost every project. I would never consider having multiple versions with different settings to speed up production. [smile]
